<maldridge>

does ldm write logs anywhere?

01:14

ok, I've narrowed it down to as near as I can tell the token LDM_THEME doesn't actually do anything. I can find no reference to it in the official documentation or the years old ubuntu documentation. I find a reference to a symlink that doesn't seem to affect anything (moving it had no affect on the theme) and there seems to be no rhyme or reason as to which theme my clients pick up at boot between the xubuntu default one, and the ltsp upstream one.

telex has left IRC (telex!teletype@freeshell.de, Remote host closed the connection)

LTSP is mostly shell and python, nothing to build there, but LDM and LTSPFS do have .c sources

06:17

LDM is the login manager and ltspfs a file system that we use for thin clients

06:18

<gehidore>

that's what caught me off guard then

06:18

was expecting to actually require some compilation, helps if I look moar closely at the sourcefiles then

06:18

I'll go back to digging around, thanks for the infos alkisg

06:18

<alkisg>

LDM and LTSPFS do need compilation

06:19

I think the wiki does have a few pointers for new maintainers

06:19

http://wiki.ltsp.org/wiki/Packaging

06:19

<gehidore>

it does have pointers, it just appears to be written by a non native english speaker *or* randomly patched together, or I'm lacking more sleep than I thought

06:20

<alkisg>

Are you talking about that ^ one?

06:20

or some other wiki?

06:20

<gehidore>

and the child pages of that page yes.

06:20

<alkisg>

OK, feel free to ask here whatever doesn't make sense

06:20

<gehidore>

just seems I might need to read this in the morning. been a long ass day already

06:20

<alkisg>

And feel free to correct any wiki errors you see

06:21

<gehidore>

aye, that's how I operate, figure this crap out and if I find errors fix em :D

06:21

<alkisg>

have a good night's sleep :)

06:21

<gehidore>

cheers alkisg , thanks for the pointers

06:27

alkisg: before I shut this sucker off, can you answer me a few questions?

06:27

<alkisg>

Shoot

06:28

<gehidore>

for humor lets assume I'm using an already supported debian setup

06:28

<alkisg>

(debian, ubuntu, mint... anything .deb-based)

06:29

<gehidore>

when a client boots will it provide a similar service such as openldap might where any user could log into any client and have access to their /home, or would I still need to come up with something like openldap configuration to make this happen?

06:29

<alkisg>

It works out of the box, you don't need to configure anything

06:29

It uses ssh for authentication and sshfs for /home by default

06:30

To switch e.g. to NFS, you modify 1 line in a configuration file called lts.conf

gehidore: if you want to try ubuntu, I've got ansible playbooks that put it together in about 15 minutes

06:32

<gehidore>

I think I've still got an f20 iso around here somewhere

06:32

sadly the connection here is less than stellar so regardless I'll have to test in the morning, appreciate your help alkisg - and the offer maldridge

06:33

probably be on in the morning bo babble some more - cheers.

06:33

<alkisg>

gehidore: f20 won't work... it's not .deb-based

06:33

Cheers

06:33

gehidore: ah,ltsp-pnp strains your connection less

06:33

Another reason to prefer it

06:34

(it builds the chroot out of the server's root disk, so no additional downloading of packages is necessary)

06:34

<gehidore>

grabbing deb 8.1.0.

06:35

<alkisg>

You'll need the debian-version of the ltsp-pnp how-to then

06:35

<gehidore>

at least on site everything is gigabit and fresh 5e wiring < 90' from my switch

06:35

oh would you suggest ubuntu then? just went for debian cause it was smaller

06:35

<alkisg>

It's a bit more complicated but I'm sure you'll manage

06:35

<gehidore>

fair enough

06:35

* gehidore wanders off

06:35

<alkisg>

ubuntu is smaller as it doesn't contain the .deb packages

06:36

<maldridge>

ubuntu uses nbd-server as opposed to nfs, which is slightly faster in my experience

06:36

<alkisg>

Ubuntu 14.04, yup

06:36

bb

06:36

About 5 times faster...

06:36

<maldridge>

alkisg: I'm bringing up pentium 2's and other ancient stuff, the bus speed is my limitation

06:37

<alkisg>

maldridge: mksquashfs compresses the data about 2.5 times, and there's also the squashfs lesser file system overhead, and the nfs chatting overhead ==> measured about 5 times faster disk access

06:38

Pentium 2's do have bus speed issues but for graphics, not for file system

06:38

And 128 MB is the lowest RAM requirement if one has Xorg running

06:38

<maldridge>

TIL, I'll have to swap a 10/100 card into one tomorrow and see if there's a noticable difference

06:39

<alkisg>

!lan-benchmark

06:39

<ltsp>

lan-benchmark: If you have a mixed-speed network (gigabit server<=>switch connection, and 100 Mbits/sec clients<=>switch connections), then you might suffer from the !flow-control issue. To benchmark your LAN with epoptes, see http://www.epoptes.org/documentation/lan-benchmark

06:39

<alkisg>

That's a very easy way to benchmark your network and client net efficiency

06:40

<maldridge>

ah iperf, yeah I should do a check, I've yet to figure out how fast any of this segment runs (my LUG has just been aquiring old hardware as the school got rid of it)

So in general bad feelings... yup this whole thing costs a lot more than just money + coin + EU

08:58

<muppis>

Yep.

08:59

Latest head line was about how restaurants keeps they cash registers in practice mode when taking receipt for tourists. When receipts are written in greek, how any non-greek speaking could notice that?

09:01

<alkisg>

It's true that corruption exists in many places, but many Greeks are honest hard workers

09:01

<highvoltage>

so true

09:01

<alkisg>

What I haven't seen a good answer for yet, is why did we have to take any loans in the first place (or in general why countries do that)

09:02

Just increase the taxes... don't take loans to get through your 4-year-duty and then leave bigger loans for the next one

09:02

So I'm pretty sure that there are other forces that orchestrate all these things
